breathing.
The ventilator continuously monitors the patient's respiratory activity. If the min-
ute volume drops below the preselected value, a mandatory breath is initiated. If
spontaneous breathing fails completely, the patient is ventilated with the selected
mandatory respiratory rate.
A 5.5.9
Flexible BiLevel
Synchronised, pressure-controlled ventilation which allows the patient to breathe
spontaneously during the entire respiratory cycle. If the measured minute volume
is above the setting (Rate x Vt), the patient is able to breathe spontaneously. BiLev -
el breaths are triggered with a dynamic adjustment of the mandatory ventilation
pressure if the minute volume drops below the setting.
With flexible BiLevel the advantages of pressure-controlled ventilation are com -
bined with the possibility of unrestricted spontaneous breathing at both pressure
levels with a constant volume.
Depending on the current lung situation, the ventilator adapts the upper pressure
level or the necessary pressure support of spontaneous breathing so that the set
tidal volume is applied with the lowest possible inspiratory pressure.
